Interfacing Load Cell with Raspberry Pi 3 (via HX711) ⚖️

Interfacing Load Cell with Raspberry Pi 3 (via HX711) ⚖️ Interfacing Load Cell with Raspberry Pi 3 (via HX711) ⚖️ A load cell is a transducer that converts force (weight) into an electrical signal. The HX711 is a precision 24-bit analog-to-digital converter (ADC) designed for weigh scales. Today we’ll connect a load cell to Raspberry Pi 3 using the HX711 module. ๐Ÿงช ๐Ÿ”ง Components Required Component Quantity Raspberry Pi 3 1 Load Cell 1 HX711 Module 1 Jumper Wires 6 Breadboard (optional) 1 ๐Ÿ”Œ Pin Connections HX711 Pin Raspberry Pi Pin Pin Number VCC 5V Pin 2 GND Ground Pin 6 DT GPIO 5 Pin 29 SCK GPIO 6 Pin 31 Figure: Load Cell connected to Raspberry Pi 3 via HX711 ๐Ÿ’ป Python Code from hx711 import HX711 import RPi.GPIO as GPIO import time hx = HX711(dout_pin=5, pd_sck_pin=6) hx.set_reading_format("MSB", "MSB") hx.set_reference_unit(1) hx.reset()...

Interfacing Sound Sensor with Raspberry Pi 3

๐Ÿ”น Overview The KY-037 is a high-sensitivity sound detection sensor that can detect noise levels in the environment. It provides both analog and digital outputs. In this tutorial, we’ll interface the digital output of KY-037 with Raspberry Pi 3 Model B+ (without using an ADC like MCP3008) and detect sound events.
